Aliadiere, now at Championship side Wolves, criticised Pardew for not giving his first-team football.
He told The People newspaper, “I would have been better off just training with Arsenal than going to West Ham.
“Alan went back on his promise because he said he would play me as a loan player and then never did.
“Ten days into the loan deal he said he wanted to sign me but once nothing came of that I didn’t have a chance.
“He told me the reason I wasn't playing was because I wasn’t a West Ham player and that I was just on loan.
“I just wasted my time because if you have the chance to train with Thierry Henry or West Ham then there isn’t a choice.
“You go to a club that is much smaller than Arsenal and you go there to play and gain experience. You don’t just go there to train and waste your time and that is what I have done.”
